The other big difference from Game 1 is Philly is protecting their defensive backboards. They gave up 23 off rebounds in Gm 1. 7 to M Robinson, 5 to J Hart, 5 to Hartenstein, 4 to Brunson.
They have only conceded 2 tonight. 16 defensive boards so a def reb rate of 89% compared to only ~50% in Game 1.
Embiid has 10 boards already. 5 off boards and 5 def boards.
